The Windmeter is an anemometer designed to measure and record wind speed distribution from 0 to 17+ meters per second. It was designed for high reliability, ease of construction, and for a wide environmental range. Data is logged over a period of 30.46 days (1/12 of a year), and then saved for 11 months. The data can be retrieved with a laptop computer any time within the 12 months of logging. The Windmeter is self-powered by a solar pannel and battery.[more]

Each encoder channel has a dedicated microcontroller, this feature gives it a high speed encoder tracking ability.It will track at up to 30 KHz ! All four channels are controlled by a main chip. The main chip takes care of calculating values for the LCD display.The main controller uses 32 bit counters so there are no practical limits for it’s use.[more]
